DOOR AND WINDOW SHADE AND CURTAIN CLAMP.

Application filed February 21, 1922. Serial No. 538,325.

To all whom it may concern:

Be it known that LLIICHAEL J. MANA- HAN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Door and Window Shade and Curtain Clamps, of which'the following is a specification.

The object of this invention is to provide means for supporting shade-rollers and curtains over the glass of doors of usual construction, on French-doors nd F rench-windows, and on windows with vertically movable sash, without marring the face of the woodwork by driving nails or screws into their finished surfaces. 7 i I The object is to make the attachment to the edges instead of to the faces of the door or window, or their frames, in a secure and simple manner subject-to easy and quick application of the holding device and its-removal. I I

I accomplish the above, and other objects which will hereinafter appear, by the mean illustrated in the accompanying drawing, in Which-'- Fig. 1, is a perspective view of my invention as applied to a. door or window, or to a window frame. Flg. 2, is a cross-section of the extension bar and end view of the curtain supporting bar and socket support for the latter. Fig. 3, is a view in cross-section of the extension bar, and an inner side-elevation of the shade-roller arm. Fig. 4, is a side-elevation and partial section of the pawl and rack mechanism for adjusting the members of the two-part extension-bar relative to each other. Fig. 5 is a cross-section of the extension-bar showing the gripping bolt securing the bar to the woodwork. Fig. 6, is a cross-section through the two lapped members of the extension-bar. Fig. 7, is a perspective view and partial longitudinal section of a modified form of curtain rod, and Fig. 8 is a modified means for adjusting the two parts of the extension bar.

Like characters of reference indicate like parts in the several views of the drawing.

My invention consists primarily of a pair of rods, here shown as angle-bars 9 and 10 made of angular material for additional stifiness and strength, held slidingly together by a loop 11, at the inner end of rod 9, and also securedtogether by a pair of standards 12'attacl1ed to the inner end of the rod 10. The standards are joined un 'der both rods at their lower ends, and between them a lever 13 is pivoted, having a single tooth which is adapted to engage with teeth formed in the upper edge of bar 9, and to move the two rods relative to each other to increase their combined lengths when the lever is lowered into contact with the rods as shown in Figs. 1 and 4. Mountdown against the expansion rods. The I pawl has an extension 18 by which it is re leased from engagement with the lever.

Passing transversely through the bars!) so and 10, beyond theirlapped portions, are the'respective grippingbolts 20, each having a sharp-edged head 21. The bolts are projected into a recess of the room caused by the thickness of the door, window, or their casing, and their heads 21 are forced into the adjacent edges of the woodwork by moving the lever 13 to increase the combined length of the rods 9 and 10, thus holding them in position. A series of holes may be provided for changing the distance from the middle of the rod, of the bolts.

Shade-roller arms 23 and 24, with the usual opening for receiving and holding the shade-roller pins, and having their inner portions bent at right angles to their bodies for substantial bearing against the casing, are provided with holes through which the respective rods 9 and 10 are passed so the arms are slidingly mounted on the rod. Undue looseness is avoided by' leatsprings 25, which are riveted to the.

arms and bear frictionally against the rods.

The arms are provided with loops, shown in dotted lines 29, Fig. 3, for supporting curare slidable on their supporting-rods to.

exact positions, after the latter are placed, and secured, in their final positions.

The application and use of my invention will be apparent from the foregoing description. It can be applied to any door or window or to their casings, although the latter have projecting molds, and where the construction makes it desirable to do so, the outer-ends of the rods 9 and 10, which have barbs 33 for the purpose, may be pressed into holding engagement without using the gripping bolts 20. i

In the modification shown in Fig. 7 a cylindrical rod 34 hassolid ends 35 telescoping therein. The ends 35 are bent and are inserted in the sockets 30. In the modification shown in Fig. 8, a pinion 36 engages with. the teeth on rod 9, as a substitute for the toothed-lever shown in Fig. 4:.

While I have here shown the best form of my invention'now known to me, it is obvious that many modifications are possible without departing from the spirit of my invention, some of which have been herein described, and I therefore do not desire to be held to the construction shown, any more thanis required by the appended claims, and having thus fully described my invention what I claim as new and wish to secure by Letters Patent is 1. A shade and curtain supporter comprising a pair of rods movable longitudinally of each other, one of said rods having a row of teeth, a pivoted lever on the other rod having a tooth engaging with the teeth on the first rod, a pawl and ratchet means for holding a given position of the lever said pawl having an extension by which it is released from, the lever, means r on the rods to enter the wood work by increase in the length of the device by a relative movement of the two rods, and shadeand curtain-holding means on the rod.

2. A shade and curtain supporter comprising a pair of rods movable longitudinally of each other, one of the rods having a row of teeth, a lever pivoted on the other rod having a member engaging'with the teeth on the first rod, adjustable means pivoted on the same pivot as the lever to prevent shortening of the combined length of the bar by engaging with the teeth of the toothed rod, means on the rod to enter the wood bv increase in the lengthof the device by a relative movement of the two rods, and shade-and-curtain holding rods.

3. A shade and curtain supporter comprising a pair of rods'movable longitudinally of each other, one of the rods having a row of teeth, a pivoted lever on the other rod having a member engaging with the teeth on th firstrod, an oscillating doublei ended pawl mounted on the same pivot as the lever, the ends of which are adapted to be brought alternately into engagement with the teeth of the bar to prevent back movement of either of the rods and conse quent shortening'of their combined lengths, means for holding a given position of the means on the v lever, means on the rods toenter the woodwork by increase in the length of the device by a relative movement of the two rods, and shade andcurtain holding means on the rod.
